Metallic Bond

The strength of metallic bonding does not depend on the size of the cation.

Ductility is the property of non-metal by which it can be converted into thin sheets.

Metals have high melting and high boiling point.

The conductivity of metal depends upon the number of electrons present in it and the _____ energy.

Why do metals have lustrous property?

Explain the Malleability by using the non-directional nature of metallic bond.

Metals have low volatility due to a strong force of attraction.

The force of attraction between metal ions and electrons is: 

A metallic bond is exists in:

Malleability and ductility of metals can be accounted due to

The element which forms ions in dimeric state is

The conductivity of the metal decreases with increases in temperature because

Which of the following does not apply to metallic bond?

Which one of the following has strongest metallic bonding?

Which of the following account for the malleability and ductility of metals?

Which of the following explain the property of metallic lustre?

Valence bond theory of metallic bond was given by

Two rods of equal lengths and areas of cross-section are kept parallel and hanged between temperatures 20$℃$ and 80$℃$. The ratio of the effective thermal conductivity to that of the first rod is (the ratio=$\frac{K_1}{K_2}$ =$\frac{3}{4}$ )

Two litres of water (density = $1 \mathrm{g} {\mathrm{mL}}^{-1}$) in an open lid insulated kettle is heated by an electric heater of power $1 \mathrm{kW}$. The heat is lost from the lid at the rate of $160 \mathrm{J} {\mathrm{s}}^{-1}$. The time taken for heating water (Specific heat capacity$4.2 \mathrm{kJ} {\mathrm{K}}^{-1} {\mathrm{kg}}^{-1}$) from ${20}^{\mathrm{o}}\mathrm{C}$to ${75}^{\mathrm{o}}\mathrm{C}$ is

Which of the following does not apply to bonding in metals ?
